Sodium Lauryl Sulfate (SLS) is a surfactant, detergent, and emulsifier used in thousands of cosmetic products and industrial chemicals as a cleansing agent. It has a degenerative action on cell membranes and is damaging to hair and skin. High levels of skin penetration may occur at even low-use concentrations. Because it is derived from coconuts, SLS is implied to be "natural," but it is mixed with sulfur trioxide or chlorosulforic acid and then neutralized with aqueous sodium hydroxide (lye).
Sodium Laureth Sulfate (shortened from Sodium Lauryl Ether Sulfate or SLES) is a yellow liquid detergent similar to Sodium Lauryl Sulfate, with higher foaming ability. SLES is considered slightly less irritating than SLS.
Talc – used in face powders and baby powders – can cause lung problems. Talc may be contaminated with asbestos.
Color Additives date back as far as 5000 years. The desire to improve one's appearance is not a modern concept. Artificial colors and dyes are now included in nearly every cosmetic product.
Many coal tar derivatives are suspected carcinogens, and most artificial colorants have not yet been tested for cancer risk. About 76 D&C (approved for use in Drugs and Cosmetics) color pigments, and approximately 19 FD&C colors are used in food and toiletries. Six FDA "certified" colors are suspected carcinogens. Others may cause hives, eye irritation and permanent blindness, behaviour problems, emotional outbreaks, attention deficit disorder (ADD), chromosome damage, and reproductive mutations. Absorption of certain colors can cause oxygen depletion of the body resulting in death.
Fragrance chemicals are added to cosmetics and toiletries. Fragrance on a label can indicate any of 4,000 individual ingredients, nearly all synthetic. Fragrance exposure can affect the central nervous system, causing depression, hyperactivity, irritability, inability to cope, and other behavioural problems. "Fragrance-free" and "unscented" products may still contain fragrance chemicals without listing them on the label. 80%-90% of fragrance chemicals are petroleum derivatives that can enter the body through inhalation, skin, or ingestion, and go directly to the brain.
